Analysis of L-probe fed-patch microstrip antennas in a multilayered spherical media

In this paper, the L-probe fed-patch microstrip antennas in a multilayered spherical media are analyzed based on the method of moments (MoM). Firstly, the structures of microstrip antennas in three-layered spherical media fed by L-probe are established as similar as the plane case. Then, the method of moments is employed to solve the mixed potential integral equation (MPIE). Numerical results for the input impedance, radiation patterns are showed good agreement with ones come from commercial software FEKO. Finally, the effects of all kind of geometric parameters on the characteristics of antenna are investigated for the next design purpose.
